# Choose a method of two-factor authentication

The Government of Canada requires the use of two-factor authentication to secure your account. You will be asked to complete registration of a second factor in order to continue to access this service.

What is two-factor authentication?

Two-factor authentication is a way to confirm users, by using a combination of two different factors:

- something they know, such as a password
- something they have, like a phone or a card

Think of it like a locked door that can only be opened with both a key and a secret code. Someone pretending to be you on the internet should never be able to obtain both the key and the code.
